Any use established in the manufacturing districts after the effective date hereof shall be operated in such a manner as to comply with applicable performance standards as hereinafter set forth governing: a) noise; b) vibration; c) air pollution; d) fire and explosive hazards; e) glare or heat; and f) radiation hazards; and no use already established on the effective date hereof shall be so altered or modified as to conflict with such applicable performance standards. Prior to issuing a certificate of occupancy, the zoning administrator may, at his discretion, require certification from a testing laboratory or professional engineer, approved by the corporate authorities, that the proposed use is capable of complying with the applicable performance standards.
1. Instrumentation: Noise shall be measured with a sound level meter, octave band analyzer meeting the applicable standards of the American National Standards Institute (ANSI S1.4-1971 and ANSI S1.11-1966). The instruments shall be set to the flat response weighing scale and the meter to the response.
2. Maximum Permitted Sound Levels:
a. Table designates the maximum permitted sound levels that apply on or beyond appropriate district boundaries. Where more than one set of sound levels apply, the most restrictive shall govern. Readings are to be made at points of maximum noise intensity. In all instances in which a manufacturing district does not adjoin a residence or business district, the performance standards governing noise shall apply at or beyond the nearest residential or business district boundary line.
b. At no point on the boundary of a residence or business district shall the sound pressure level of any individual operation or plant (other than background noises produced by sources not under control of this title such as the operation of motor vehicles or other transportation facilities) exceed the decibel levels in the designated octave bands shown in table I of this section.
c. For impact noise levels, the values in table II of this section shall apply. For purposes of this title, "impact noises" shall be considered to be those noises whose peak values are more than three (3) dB higher than the values indicated on the sound level meter.
TABLE II
IMPACT NOISE LIMITS
1. Instrumentation: Ground transmitted vibration shall be measured with a seismograph or complement of instruments capable of recording vibration displacement, particle velocity, or acceleration and frequency simultaneously in three (3) mutually perpendicular directions.
2. Maximum Permitted Vibration Levels:
a. Table I of this section designates the maximum vibration limits that apply on or beyond adjacent lines within the zone, and on or beyond appropriate district boundaries. Vibration shall not exceed the maximum permitted particle velocities listed in table I of this section. Where more than one set of vibration levels apply, the most restrictive shall govern. Readings may be made at points of maximum vibration intensity.
b. The maximum particle velocity shall be the maximum vector sum of three (3) mutually perpendicular components recorded simultaneously. Particle velocity may also be expressed as 6.28 times the displacement in inches multiplied by the frequency in hertz (cycles per second).
c. For purposes of this title, steady state vibrations which are continuous, or vibrations in discrete impulses more frequent than sixty (60) per minute, shall be considered impact vibrations.
